Narrative: When we got to the site, there was a lot of debris on the ground due to a big storm that occurred a few days beforehand. The debris made it difficult to find certain flowers but we were able to find most of them. At one point, we were looking for mouse-eared monkeyflowers. The first person to find it would get extra credit but Dr. Paul found it instead. So no extra credit. There were also a lot of muddy areas so we had to walk carefully. The weather was really nice as well.
